SoilFixer SF60 is a super soil improver - think of it as "super compost". Made in the UK using our propriety formulation of activated (enriched) biochar, colloidal humus, plant macro and micro nutrients.

Ready to use by gardeners and allotment growers who want to improve their soils and container growth mixes to the best they can be.

For those seeking better plant and vegetable growth. In our SF60 tests, we have seen increase in plant and crop growth of 100% over the control soil. All plant growth testing is complex and it takes many test replications over a number of years before the average increase can be quoted. We believe most users can conservatively achieve +20% increase.

How does SF60 work

The biochar/colloidal humus matrix acts as ‘sponge’ for water and essential nutrients – storing them ready for use. The ‘sponge’ matrix supports increased levels of soil microbes. The microbes (notably mycorrhizal fungi) can access the stored nutrients. They form symbiotic relationships with plant roots and supply nutrients to the roots. This mechanism is sometimes described as ‘improved soil health leading to improved plant growth’. (More detail around SF60, the role as an improver versus fertiliser, versus compost can be found in our SF60 FAQ blog post)

The biochar and colloidal humus in the SF60 product remains in soil year after year. You can top-up and build towards 20% target by adding a bit more each year.
